VAPOUR Flow Control Solutions

3-way Mixing Valve and Evaporator

Bronkhorst^® model W-303B CEM 3-way Mixing Valve and Evaporator is suited for precise vapour flow delivery, composed by mixing up to 1200 g/h H₂O (3200 g/h IPA) with max. 100 l_n/min of carrier gas at operating pressures between vacuum and 100 bar. The temperature controlled mixing device is used in combination with a (thermal or Coriolis) liquid flow meter and an MFC for carrier gas, together forming a Controlled Evaporation and Mixing (CEM) System.
